The Dallas Cowboys confirmed their starting quarterback broke a bone in his back during Thursday’s preseason game against the Seattle Seahawks, and multiple reports are citing Romo’s timetable as a minimum six- to ten-week recovery period.

Jason Garrett: Tony Romo had an MRI on Friday, and he has a broken bone in his back.

Cowboys head coach Jason Garrett insisted in a conference call with media members that Romo was “day to day,” according to NFL.com, but NFL Media’s Ian Rapoport and Pro Football Talk were among those reporting that was unlikely.

My understanding is that best-case scenario is that #Cowboys QB Tony Romo returns by mid-season. He broke a different bone than last time.

Romo has broken bones in his back before (and missed 12 games last season with two separate injuries to his left collarbone), but this time he broke a different back bone, and it seems the injury is much worse.

The broken bone is an injury that may linger for #Cowboys QB Tony Romo this season. I'm told he'll likely need an epidural to play.

Rookie backup QB Dak Prescott, who has set the NFL ablaze this preseason, is expected to start Week 1 against the New York Giants, becoming just the fourth rookie QB ever to start Week 1 for the Cowboys. Two of the other three? Hall of Famers Roger Staubach and Troy Aikman. Just sayin’.

Should Prescott continue to light it up in Romo’s absence, we might have a serious quarterback controversy on our hands.
